PRO1 Single-channel, PRO2 Dual-channel, PRO4 Four-channel True Diversity Wireless Conference Microphones
(Equipped with network port cascading, equalization adjustment, sweep frequency meter, and coding setting functions)

Product parameters:
1. Advanced digital pilot technology is adopted. Each channel is equipped with an independent ID code to eliminate the phenomenon of frequency crossover. The stable PLL phase-locked oscillation circuit, combined with the "Noise Detection" silent control function, can effectively block the noisy radio frequency interference in the environment. The true diversity four-channel antenna system, with an integrated antenna distribution system, features single-channel AB intelligent reception, effectively enhancing dead point handling, achieving long-distance reception without frequency interruption, and capable of handling various complex performance environments.
2. The intelligent receiver has a self-sensing function for sensitivity. In complex usage environments with a wide effective distance, when the system detects weak on-site environmental signals, it can automatically increase the receiving sensitivity, with a maximum enhancement of 15dbm.
3. The system features a dual 25MHz bandwidth and a 50MHz step design, allowing you to adjust the frequency more precisely and improve the frequency utilization rate.
4. The entire series of products are equipped with full-color high-definition 2.0-inch TFT displays, supporting both Chinese and English menus. It enables quick switching of system languages. The system interface allows for visual Settings of functions such as machine numbering, output sensitivity, group selection, equalization, spectrum, network frequency division, and system Settings.
5. One-click full-frequency radar scanning: Press the scanning key and the full-frequency scanning can be completed within seconds. Set the corresponding microphone to match and automatically and precisely lock the working frequency point of receiver.
6. The system is equipped with a real-time spectrum monitoring function, featuring a full-band scanning search for frequencies. It can detect the on-site environment and display the existing frequencies and intensities in the space. It enables intuitive selection of clean operating frequencies within the spectrum, making frequency modulation visual and more intuitive and accurate.
7. The system provides 10 preset groups. When the frequencies within each group are shared by multiple receivers in the same situation, the frequency table for stacking can be retrieved to quickly plan frequency groups that do not interfere with each other, achieving efficient stacking usage.
8. The system has five EQ high and low frequency balance options with different setting modes.
9. Receiver has a channel number setting function, which can set the number of each channel separately. After microphone and receiver are synchronized in frequency, the corresponding channel number is displayed synchronously to avoid channel confusion and improve on-site operation efficiency.
10. It has the function of network frequency division, a data transmission network port, and supports one-click switching and synchronization when multiple receivers are cascaded. After receivers are cascaded, this function can be used to quickly and automatically allocate clean frequencies to all cascaded devices.
11. Each channel of receiver can store two frequencies in memory, and it can intelligently and seamlessly switch between bodypack, handheld and conference microphones with one click, liberating the complex frequency matching process (in network connection mode, other machines can also switch simultaneously).
12. Receiver has 31 levels of audio output gain options, allowing users to select the appropriate audio output volume based on on-site requirements.
13. Conference microphone is equipped with a 16MM gold-plated diaphragm microphone core, and its effective pickup distance can reach over 40-80cm.
14. Conference microphone base is made of all-metal die-casting in one piece, with a high-end frosted and painted finish, and is a patented appearance product.
15. Conference microphone base is equipped with a built-in mute function button to prevent unnecessary howling caused by the use of multiple microphones.
16. Conference microphone built-in detachable high capacity 18650 lithium battery, base with TYPE-C charging interface, can be charged separately, full of intelligent power off, safe and assured, for your long conference use escort. Equipment delivery 18650 batteries and TYPE-C dock.
